PROXIMITY COUPLED RECTANGULAR MICROSTRIP PATCH ANTENNA FOR S-BAND APPLICATIONS

Abstract

Microstrip antennas have been one of the most featuring topic in antenna theory and design in recent years, and are progressively more finding application in a wide range of modern communication systems. In this study a microstrip antenna has been designed using proximity coupled feeding technique. The proposed antenna uses two layered substrate, such as the patch antenna on upper layer and the microstrip feedline on the lower layer. The study is made using the thickness of the substrate material. The experimental result shows that the Proximity coupled Rectangular Microstrip Antenna (PRMSA) gives an impedance bandwidth of 3.97% (110MHz) and 17.17% of gain. Also the other antenna parameters such as radiation pattern, reflection coefficient, VSWR and HPBW are calculated and discussed.
